MIXING APPARATUS.

Continuation of application Serial No. 329,148, filed October 7, 1919. This application filed September 24, 1920. Serial No. 412,497.

T0 all wh m/'1: it may concern Be it known that I, VVILLIAM CLAUSON, a subject of the King of Sweden, residing at Everett, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Mixing Apparatus, of which the following is a specification.

My invention relates to a mixing or spraying apparatus for use in spraying or wash ing objects with a liquid or a liquid solution. The object of my invention is to provide an improved device or apparatus of this kind adapted for use in washing automobiles and other vehicles, in washing floors and walls, spraying trees and other work involving the application of a liquid or a liquid solution.

I am aware that mixing and spraying devices of various kinds have been heretofore invented which are devised to operate by diverting from a main stream of liquid under pressure a branch streainwliicli flows into a container or chamber containing chemical orsoap, the diverted liquid with the chemical or soap which it'entrains then reuniting with the main stream. N one of the e devices, however, have the combination of elements of my new apparatus upon which I rely for its successful operation.

The utility of my device is well demonstrated by its use inthe washing of automobiles and other vehicles.

Heretofore in washing automobiles and other vehicles it has beenthe usual practice to apply a mixture of soap and water by means of a sponge, the soap commonly used being furnished to garages by the barrel and in the form of a paste. The worlnnan engaged in washing a vehicle usually scoops up a handful of the soap paste from the barrel and deposits it in a pail. containing water in which latter the soap is dissolved by stirring. No measurement is made of the soap used for each pail. of water other than the amount selected by the workman in scooping a handful from the barrel, and no great care is used in dissolving the soap in the Water with the result that the workman in most instances uses more soap than neces sary and almost invariably an undissolved quantity ofthe soap remains unused 1n the bucketand is thrown away when the latter is emptied. As a result a great'amountof soap is wasted. In my invention is embodied a cally to mix soap With the water as the latter, passes through said apparatus, and to throw onto the automobile a spray of soap suds. In its preferred form the apparatus is supplied with a control valve which controls the flow of .Water and the flow of soap suds whereby the apparatus may deliver clear Water directly from the source of supply, or soap suds from the container, or any desired mixture of the two.

lVith this and other objects in view my invention consists in the combination of parts set forth in the following specification, and particularly pointed out in the claims thereof.

In the accompanying drawings:

Figure l is a plan view of a mixing apparatus constructed in accordance with my invention Figure 2 is a section on line 2--2 of Figure 1;

Figure 3 is a section on line of Figure 2; I

Figure 4: is a section on line t4 of Fig ure 3;

Figure 5 is a section on line 55 of Figure 2; and c Figure 6 is a section on line 6-6 of Figure 2.

The apparatus herein shown comprises a vessel 1 of sheet metal closed at its top by a cover 2 which may be soldered to said vessel. To the cover 2 is secured, as by rivets, a non zle 3 having an enteriorly threaded end 4 adapted to be coupled to the end of a flexible hose pipe by means of which the nozzle is connected with a faucet or other supply of water under pressure or head. Within this inlet end of the nozzle 3 may be provided a screen disc 5 made from wire cloth. Nozzle 3 is made with a main port 6 therethrough of relatively large size which is controlled by a tapered valve 7 rotatably mounted within a transverse valve chamber 8. At its outer larger end the valve 7 is made with a handle 9 by means of which it is manually rotated, said larger end'being also provided with a laterally projecting pin 10 co-operating with a lug 11 on the body of the nozzle for the purpose hereinafter set forth. At its smaller end the valve 7 is formed with a stem 12 that is transversely p'erforatedto receive a cotter pin 18 which holds a washer 1a in place on said stem. On this stem 12 is also mounted aspring' 15 one end 01 which bears against the washer 14 and the other end against another washer 16 keyed in the usual fashion to the stem. The spring 15 servesto hold the valve seated within its chamber.

The nozzle-Sis madewith another port 17 opening into valve chamber 8 at right angles to the port 6, said port 17 communicating with a pipe 18 01 relatively large capacity which in turn has connected with it the upper end of a pipe 19 of relatively smaller capacity Whose lower end is near the bottom of vessel 1 and inclosedby a porous hood 80prefer'ably made from wire cloth.

This lowerend of the pipe 19 constricted as shown, permitting a comparatively'sniall outlet from the pipe 1,9"into".the vessel;

l/Vithi'n the poroushood 2O arranged the. lower end of another pipe 21 wlt ich extends upwardly tothe nozzle 3 where its upper end opens into a chamber 22 provided at the discharge end of the nozzle. This chamber 22 communicates with the port 6 through a horse-shoe shaped slit 28, Figures2 and 5, which is in-close roximity to the discharge end of pipe 21. I

One end of 'a by-pass 32, of relatively small capacity, is connected to the lower end of pipe 18 and'the opposite end'ot pipe 32 opens into pipe 21 so-as to discharge toward the outlet end thereof. The pipe 32 is of smaller capacity than pipe 21. The constriction at the lowerend of pipe 19 and the relatively small size of the by-pass pipe 32 make the capacity of pipe 18 greater than the other two with the result that a portion of the stream diverted into pipe 18 isforced under pressure through pipe 82 into pipe 21, producing" the action or effect of an injector at 33 which establishes and 'maintains a flow of soap sudsfrom thecontainer up through pipe 21. The capacity of the pipe 21 and the flow produced therein by the ejector 3" is sui'licient to discharge the liquid which flows into the container force pipe 19 as the apparatus operates, so that the container never fills up and overfiows.

The valve 7 is a three-way valve. That "is, it is formed with a transverse port 25,

valve 7 is thus opened, which causes'water to flow from port 6 through ports 25, 26 and 17 and from the latter through pipes 18 and 19 into vessel land through-by-pass 32 with the injector effect above described.

The top of the vessel 1 is made with a door 27 connected with the cover plate 2 by hinges 28. This door 27 normally closes an opening 29 through Whichaquantity of soap paste'is passed into vessel 1. It will thus be seen that the water discharged into the vessel through the pipe 19 is brought into contact with this body of soap, some of which it entrains so that the water leaving thevessel through'pipe21 issoapy.

The soap suds dischargefrom thepipe'21 in the direction of the top of the chamber 22 where they are struck by thespray-ot water which rushes under pressure from the slit 23 and which carries the soap sudswith it onto the automobile or other ob jectto' be sprayed or washed. The arrangement is such that a steady, strong stream of soap suds or soapy water is'throwfn from theend of the nozz1e'8 directly onto the object that is being cleaned.

When it is desired to wash the objectwit'h clear water the valve 7 is moved in a left hand direction into a position ninety degrees from that shown in the drawings which brings the port 25 into alignment with port 6 and closes port v17. Aswill be clear the purpose of the hood 20'is to keep the soap paste within Vessel '1 away "from the lower ends of the pipes 19 and 21 so that the latter cannot become cloggechand at the same'time the porous characterofthis hood permits the water to pass back and forth therethrough as is necessary.

The soapf paste commonly used is more or less stiff and may sometimes be forced into the vessel 1" by a rigid poker tl'ia-twou-ld 'be likely to injure the small pipes 19' and" as well as the hood120'ispermitted to engage the same. Forthi's reason I provide within the vessel 1 a guard 30 in the shape of a wall depending from cover 2- and extend-'- ing downwardly --fai-' enough to shield said. parts. 7

The body of the nozzle 8 is made with a disc-like enlargement 31 bearing four'index marks in the form of arrows as shown in Figure 1, said marks being angular'ly positioned with relation to the handle 9 so as to co-operate with the -la-tter as an index for use in positioning the valve 7, inscriptions Stop, Soap and water, Slow, and Clear water or the like informing-the user as to the action of the apparatus for each position of the handle indicated by the arrows. When the handle 9 is positioned .at the arrow, Soap and water, the maximum amount of soapy water is mixed with the steam discharging from the nozzle, and by moving the handle 9 from this position in a right-hand direction toward the stop lug 11 the amount of soapy water supplied to the discharging stream may be decreased to the minimum which latter is secured when the pin 10 engages the lug 11. This position is useful when it is desired to simply soap the sponge. lVith the handle 9 registering with the Clear water position the size and speed of the stream may be varied by adjustment of the handle and valve in either direction from that position, the engagement of the pin 10 with the lug 11 stopping the valve in position to deliver from the nozzle a slow small stream of clear water such as would be desired in wetting a sponge, or for washing off the soap suds.

The apparatus herein. shown is constructed as an attachment adapted to be coupled to the end of a flexible hose pipe which in turn may be connected with the faucet of a. water system, the apparatus being grasped by one hand and manipulated to direct the stream upon the object being cleaned. F or this reason the vessel 1 is preferably made upon its exterior with a handle 83 across the top of which the hose pipe will extend when the latter is coupled to the nozzle, so that both the handle 33 and the end of the hose pipe are grasped by the hand of the workman when the apparatus is in service. This prevents abrupt or sharp bending of the hose pipe near its junction with the nozzle.

The improved mixing apparatus above described is of simple, efficient and inexpensive construction. Its use not only results in great economy in the consumption of soap and water but makes it possible to perform the operation of washing a vehicle quickly and effectively. not depend upon pressure within the container to discharge the contents of the container from the apparatus so that the container need not be air tight and the entire operation can be cont-rolled by one valve.
